The Town Council finds that the Final Revised EIR has been prepared in compliance with CEQA, and reflects the independent judgment and analysis of the Town of Danville. Section 2. The Town Council declares that it has made a reasonable and good faith effort to eliminate or substantially mitigate, through adoption of all feasible mitigation measures, all potentially significant impacts that may result from the Project. Section 3. The Town Council concurs with the CEQA Findings and Statement of Overriding Considerations in Exhibit 1 to this Resolution and incorporated herein by this reference and finds, that if an environmental impact remains significant and unavoidable, the benefits of the Project outweigh any potential significant and unavoidable environmental impact. The Town Council also concurs that there are no additional feasible alternatives or mitigation measures within its powers that would substantially lessen or avoid any significant and unavoidable impacts that may result from the Project. Section 4. The Town Council certify the Final Revised EIR for the Project and approve the Project. Section 5. The Town Council authorize that a Notice of Determination shall be filed within five working days of approval of the Project. And, be it further RESOLVED, that the Danville Planning Commission recornmends that the Town Council approve Preliminary Development Plan - Rezoning request (LEG10-0004), Major Subdivision request (DEV10-0071), Final Development Plan request (DEV10- 0072), and Tree Removal request (TR10-0028) per the conditions contained herein, and makes the following findings in support of these actions: FINDINGS PRELIMINARY DEVELOPMENT PLAN - REZONING The rezoning of the site to P-1,; Planned Unit Development District is consistent with the Town of Danville 2030 General Plan. The General Plan contains policies that encourage clustering of development on flatter portions of properties to preserve open space and natural features. 2030 General Plan Policies 1..07,2.05, and 21".02 contain such provisions, with Policies 1.07 and 21..02 specifically identifying PUD or P-1 zoning as implementation measures. 1 PAGE 4 OF RESOLUTION NO.2019-05 2.The project site is identified as a Special Concern Area in the General Plan. The text for the Special Concern Area of the Magee Ranch property (on pages 3-49 and 3-50 of the 2030 General Plan) includes the following relevant direction: . The Plan deseribes Diablo Road in this area as retaining "the character of a country road. The Town strongly supports retention of this character and protection of the views and vistas from the road." o "[P]roposals which transfer the allowable number of homes to the least sensitive and obtrusive parts of the site are encouraged." o "As on the other large undeveloped hillside sites in Danville, protection of scenic slopes and ridgelines is imperative. Despite the A-2 (General Agricultural) zoning on much of the site, subdivision of this Special Concern Area into five-acre 'ranchette' sites similar to those in the Tassajara Lane/Sherburne Hills area is strongly discouraged. Such development would require grading and road construction that could substantially diminish the visual qualities of the area. Transferring allowable densities to a limited number of areas within the ranch would enable the bulk of the site to be set aside as permanent open space. This would also provide opportunities to establi.sh park and trail connections and to preserve wildlife corridors between this area and the Sycamore Valley Open Space. P-1 zoning is the only zoning designation that permits this clustering of potential development, without creation of S-acre "ranchettes," which the Special Concern Area language specifically discourages on the property. With clustering, the new residences would not be visible to motorists on Diablo Road. Approximately 381 acres of the project site would be set aside as permanent open space and two miles of trails would be dedicated to create connections to the Sycamore Valley Open Space. The Town further finds that the rezoning for residential development is within the maximum permitted density under the existing General Plan land use designations on the property, which include Single Family-Low Density, Rural Residential, Agricultural and General Open Space. The uses authorized or proposed in the land use district are compatible within the district and to uses authorized in adjacent districts. The proposed infill housing is an efficient development pattern consistent with surrounding residential subdivisions and will add to existing infrastructure that services the adjacent single family residential uses. 3. 4. PAGE 5 OF RESOLUTION NO. 201.9.05 't. FINAL DEVELOPMENT PLAN - MAIOR SUBDIVISION The proposed subdivision is in substantial conformance with the goals and policies of the 20L0 General Plary including the requirements of Measure S. The Town's 2030 General Plan recognizes the site as an important site that merits specific direction for its development. As such, the site is designated as one of 11 Special Concern Areas within the General Plan. The Special Concern Area language includes the following provisions, which are addressed through the proposed project: . The Plan describes Diablo Road in this area as retaining "the character of a country road. The Town strongly supports retention of this character and protection of the views and vistas from the road." The project residences would be clustered at the lowest, flattest areas of the project site, where they would not be visible to motorists on Diablo Road. o The Plan provides that "[P]roposals which transfer the allowable number of homes to the least sensitive and obtrusive parts of the site are encouraged." The clustering of homes would comply with this directive. . The Plan provides that "As on the other large undeveloped hillside sites in Danville, protection of scenic slopes and ridgelines is imperative. Despite the A-2 (General Agricultural) zoning on much of the site, subdivision of this Special Concern Area into five-acre "ranchette" sites similar to those in the Tassajara Lane/Sherburne Hills area is strongly discouraged. Such development would require grading and road construction that could substantially diminish the visual qualities of the area. Transferring allowable densities to a limited number of areas within the ranch would enable the bulk of the site to be set aside as permanent open space. This would also provide opportunities to establish park and trail connections and to preserve wildlife corridors between this area and the Sycamore Valtey Open Space." The project, through the use of P-1 zorrirng to cluster the permitted development, would avoid creation of "ranchette" sites, would limit grading and road construction and substantially preserve the visual quality of the area. The clustering of the project would also permanently preserve 381 acres, or approximately 93% ol the site as open space, which would include trail connections to the Sycamore Valley Open Space, provision of easements necessary to create a bicycle/pedestrian trail parallel to Diablo Road, and preservation of wildlife corridors through the site. The design of the proposed subdivision is in conformance with the P-1; Planned Unit Development District since the subject P-'1"; Planned Unit Development District is customized to the subject Development Plan. The P-1; Planned Unit Development District is an appropriate zoning designation for infill projects and 2. PAGE 6 OF RESOLUTION NO. 2019-05 3 4. lands designated as Special Concern Areas in the General Plan. Additional detailed findings regarding P-1 zoning consistency can be found under Preliminary Development Plan - Rezoning above. The design of the subdivision and the type of associated improvements will not likely cause serious public health problems, because water and sanitary facilities services will be available to the'new parcels. The site of the subdivision is physically suitable for the proposed density of development. The proposed development of 69 lots on the 410 + /- acre site falls within the allowable maximum density range of up to 78 units, consistent with the site's Danville 2030 General Plan land use designations of Residential - Single Family - Low Density, Rural Residential, Agricultural and General Open Space. With respect to density on the portions of the site designated as'{Agricultural" irt the 2030 General Plan, the General Plan provides the following: "Because properties with this designation are bound by Williamson Act contract to remain in agricultural uses, a density range is not applicable. In the event that Williamson Act contracts are not renewed, continued agricultural use is encouraged and the underlying zoning density (one unit per 20 acres or one unit per five acres) would apply upon the contract expiration." The portions of the site designated as Agricultural are no longer bound by Williamson Act contract. In such situations, the Town's practice (and that of Contra Costa County, prior to the Town's incorporation in 1982) was to zone lands to A-4 (20 acre minimum) upon execution of a Williamson Act contract, regardless of the size or prior zoning of the property. The purpose of this A-4 zoning designation is to show that the property is under a Williamson Act contract. For example, the Town rezoned the "Borel" property (APN 218-090- 031) from P-L to A-4 upon execution of a Williamson Act contract, despite the entire parcel being orly 17 acres. Under the A-4 zoning designation one home per 20 acres is allowed Upon expiration of a Williamson Act contract, the General Plan dictates that the Town apply the "underlying" zoning, which has been the zoning in effect prior to entering into the contract. This reflects the intent to place the property in the position it held prior to entering into the contract, neither increasing nor decreasing the property's development potential. This practice was previously applied by the Town with respect to Assessors Parcels 202-100-017, -018, and -0L9 on the subject property. In February 1986, the Town approved a Williamson Act contract for these parcels and at the same time adopted an ordinance rezoning PAGE 7 OF RESOLUTION NO.201.9-05 5 6. them from A-2to A-4. In March 1988, after discovery that the contract had never been properly executed, the property owner requested, and the Town approved, an ordinance rezoning the property back to the prior designation oÍ A-2. The propertv owner in this case did not apply to rezone the property after the Williamson Act contract expired. Flowever, in determining potential density for purposes of this applicatiory the Town used the underlying zoning oÍ A-2 (with the corresponding maximum development density of one unit per five acres) as provided for in the General Plan and consistent with prior applications, including the Elworthy Ranch project approved by the Town in 2008 under the approval granted for Preliminary Development Plan - Rezoning request PUD 2005-02. The design of the proposed subdivision and improvements are not likely to cause substantial environmental damage or subsequently injure fish or wildlife or their habitat. The Revised Environmental Impact Report prepared for the project found that, with implementation of recommended mitigation measures, the project would have no significant negative impacts on the wildlife on site, including California Red Legged Frogs, wetlands, trees and plant life. The design of the proposed subdivision and proposed improvements will not conflict with easements, acquired by the public atlarge, for access through or use of property within the proposed subdivision. There are currently no existing public easements for access through or use of the subdivision. Through project conditions of approval, the subdivision will offer new easements for public access. The project will not cause on-site flooding or add to existing downstream flooding as detailed in the Hydraulic Report prepared for the project by ENGEO, Inc. and as concurred with by the Contra Costa County Flood Control and Water Conservation District. TREE REMOVAL PERMIT The project as proposed would preserve2T2 trees out of the 321 surveyed trees and tt ury other trees located throughout the site, and remove 49 trees. Of the 49 trees to be removed, seven are designated as protected trees under the Town's Tree Preservation Ordinance. In addition, to construct roadway improvements at and near the intersection of Diablo RoadlGreen Valley Road/McCauley Road, the project would remove L8 trees, including eight protected trees. 7 PAGE 8 OF RESOLUTION NO.2019-05 1. The findings below address only the l-2 trees designated as protected under the Town's Tree Preservation Ordinance. The EIR for the project analyzes the potential environmental impacts of removing all trees, whether or not they are designated as protected. Necessit]¡. The primary reason for removal of the 67 trees, including 15 Town- protected trees, is that preservation of those trees would be inconsistent with the proposed residential development of the property, including the creation of a new roadway to access the main project area, including a new creek crossing, to be located east of ]illian Way, and the widening of the Diablo Road/Green Valley Road/McCauley Road intersection to the south to improve the function of that intersection. 2.Erosion/surface water flow. Removal of the L5 Town-protected trees and 67 total trees would not cause significant soil erosion or cause a significant diversion or increase in the flow of surface water. 3. Visual effects. With respect to other trees in the area, the project site contains a significant number of additional trees, including Town-protected Oak trees, that would not be removed for the project. In additiory the project proponent will be required to replace all Town-protected trees to be removed with approved species "of acumulative number and diameter necessary to equal the diameter of the tree(s) which are approved for removal" in accordance with the Town's Tree Preservation Ordinance. Tree replacement will be conducted in accordance with the Town's requirements, including planting a mixture of small and large box trees to meet the cumulative diameter number of the removed trees. The project proponent will also be required to replace all non-ordinance-size trees (i.e., trees less than 10 inches in diameter for single-trunk trees or less than 20 inches in diameter for multi-trunk trees) at a replacement-to-removal ratio of 1:1. Removal of the 67 trees, including 15 Town-protected trees, would not significantly affect off-site shade or adversely affect privacy between properties due to the site's topography, the other trees that would remairy and the locations of the trees in relation to other properties.

The project proponent shøIt retøin a quatified biologicøl monitor to be present o;nsite during times of construction ruithin the riparian høbitat of East Branch Green Vølley Creek to ensure no CRLF øre hørmed, injured, or killed during projectbuildout. The project uould impøct approximately 0.3 acres of moderate-quølity riparian habitøt resulting from construction of the aehiculør bridges across Eøst Brønch Green Vølley Creek. The project shøll repløce the lost oølue of this impact by restoring the impøcted ripøriøn hnbitat øt ø minimum 'l-:1 replacement-to-loss ratio. (Final mitigation amounts ruill be based on øctual impacts to be determined during the design phase.) This shall be accomplishedby restoring ripariøn høbitnt øt the four folloruing locations: The existing uet crossing ønd øsphølt neør the pønhøndle (.e., uthere the nezu bridge is to be constructed) shøll be remoaed. The silt and sediment buildup behind and ødjacent to the utet crossing and øsphnlt shall also be remoaed and the creek bed shøll be lozuered to restore the natural floru of this portion of the creek. limited to single story homes only. The existing crossing from Søn Andreas Driae shøll be remoaed and the creek restored in this area. b PAGE 22 OF RESOLUTION NO. 2019-05 c.The tr.uo existing cøttle grates on Magee West near the existing culaerts shall be remoued.

Define the financiøl mechanism for the GHAD to mønage the open space into perpetuity. C. d e f, (,ô 5 Prior to the start of construction, the project proponent shøIl retøin ø qualified biologist to trøin construction personnel regørding habitøt sensitiuity, identiflcøtion of speciøl status species, ønd required practices. Prior to the størt of construction zuithin the East Brønch Green Valley Creek ripørian areø, the project proponent shall retøin ø qualifed biologist to conduct pre-construction suroeys to ensure that zoestern pond turtles are absent from the construction ørea. If ruestern pond turtles are present, ø qualified biologist possessing øIl necessdry permits shøll be retained to relocate them. If utestern pond turtles are found to be absent from the construction zone, immediately follouing the pre-construction suraeys the project proponent shøll cleør the construction zone ønd instøll/maintain silt fencing øround the construction zone to preaent utestern pond turtles from entering these øreøs. During construction ruithin the Eøst Branch Green VøIIey Creek ripariøn area, the project proponent shøll retain a biological monitor to be present onsite during times of construction to ensure that turtles are not harmed, injured, or killed. 6. 7 8 PAGE 24 OF RESOLUTION NO. 2019-05 9 To the maximum extent prøcticøble, the project proponent shall remoae trees during the non-breeding seøson (September 1 through lnnuary 3L). If it is not possible to øooid tree remoaøl and associøted disturbances during the breeding season (Februøra 1 through August 3'1.), the proiect proponent shøll retøin n qualified biologist to conduct a pre-construction surrey for tree=nesting røptors and other tree- or ground-nesting migratory birds in øll trees or other areas of potential nesting høbitat zoithin the construction footprint and 250 feet of the footprint, if such disturbance utould occur during the breeding season. This suft)ey shøll be conducted no more than L4 døys prior to the initiøtion of demolition/construction øctirtities during the eørly pørt of the breeding season (February through April) ønd no more than 30 days prior to the initiation of these øctiaities during the late part of the breeding seøson (Møy through August). If nesting raptors or migrøtory birds are detected on the site during the suraey, ø suitable construction-free buffer shøll be estøblished around all øctiae nests. The precise dimension of the brff , (ø minimum of 150 feet up to a maximum of 250 feet) shnll be determined øt thøt time and møy uary depending on location and species. Buffers shall remnin in place for the durøtion of the breeding seãson or until it høs been confirmedby a qualifiedbiologist that all chicks hnae fledged and are independent of their parents. Pre-construction suraeys during the non- breeding season are not necessnryt as the birds are expected to abandon their roo sts during construction øctiaitie s. In order to øaoid impacts to actiae burrowing outl nests, the project proponent shøIl retain ø qualified biologist to conduct pre-construction suraeys for burrouting owls utithin the construction footprint and within 250 feet of the footprint no more than 30 døys prior to the onset of ground disturbance. These sulveys shall be conducted in a mnnner consistent uith the CDFG's burrouting orul suraey methods (CDFG 2012b). If pre-construction surceys determine thøt burroruing owls occupy the site during the non-breeding seøson (September L through January 31), then ø passiae relocøtion ffirt (e.g,, blocking burrows zoith one4L)øy doors and leauing them in place for a minimum of three døys) may be used to ensure that the oulls are not harmed or injured during construction. Once it høs been determined that ontls høae aacnted the site, the burrous can be collapsed, and ground disturbance can proceed. If burrouting or.ols are detected within the construction footprint or immediøtely adjacent lands (i.e., within 250 feet of the footprint) during the breeding season (February L through August 3L), ø construction-f'ree bufft of 250 feet shall be estøblished øround øll øctiue oul nests. The buffer areø should be enclosed utith temporary fencing, ønd construction equipment and utorkers møy'not enter the enclosed setback nreøs, Buffers must remøin in pløce for the duration of the breeding season or until it has been confirmed by a qualified biologist thøt all chicks hate fledged and øre independent of their pørents. After the breeding seøson, pnssiae relocøtion of any remøining outls møy tøke place øs described øbozte. 10. PAGE 25 OF RESOLUTION NO.2019-05 11. 12. Pre-construction surveys conducted for burrortting outls shøll ølso be used to dBtermine the presence or øbsence of bødgers in the deaelopment footprint. If øn øctiue bødger den is identified during pre-construction sulz)eys utithin or immediately adjacent to the construction enaelope, the project contractor shøll establish ø construction-free buffr, øround the den of up to 300 feet or a distance specifiedby the resource agencies (i,e., CDFG). Becøuse badgers are knoutn to use multiple burrouts in ø breeding burrout complex, the project contrøctor shøIl retain a biologicøl monitor during construction actiaities to ensure the bffir is adequøte to øaoid direct impacts to indioiduals or nest abandonment. The monitor shøll be present onsite until it is determined thøt young are of an independent age and construction actiaities ruould not harm indiaiduøl bødgers. Once it høs been determined that badgers haae uøcated the site, the burrours can be collapsed or excaaøted, ønd ground disturbance cøn proceed. The project proponent shøll replace rttetland ønd riparian hnbitøt øt ø 1:L repløcem.ent-to-loss røtio. It is expected that all compensation measures can be accommodated uithin the 38L acres of the site proposed øs open spøce. Prior to issuance of a grading permit, the project proponent shall retain a qualified biologist to prepare an onsite habitøt mitigation and monitoring pløn (HMMP) thøt includes both øn aquøtic høbitøt res,toration pløn and a ripørian høbitat restorøtion pløn. The HMMP zoould specifically øddress the utetland and rþarian habitøts and is separøte from the Open Space Mnnøgement Plan identified in Mitigation 4.4-4, øIthough there mny be some ozserløp. The HMMP shall include the following components, at a minimum: Define the location of all restoration/creation actiaities; Proaide eaidence of a suitøble zttater budget to support øny created rue tland ønd rþ arian høbitats ; Identifu the species, ømount, andlocntion of plønts to be installed; Identify the time of year for planting and method for supplementøI roatering during the establishment period; Identify the monitoring period, urþ¡r¡ should be not less than 5 yeørs for zuetlønd restoration ønd not less than '1-0 years for riparian restoration, defines success criteriø thøt tuill be required for the zttetland restoration to be deemed n success; Identify adøptiae managernent procedures that include þut are not limited to) meøsures to address colonizøtion by inaøsiae species, unexpected løck of water, excessiae foraging of installed zoetland plants by natiae ruildlife, and similar; ø. b. c. d. e f.
